Ooops I often make mistakes like that Kanji combinations with similar outlines and whatnot.

This なんか is the same as なんて, which gives the "a loser like you" in my (loose) translation. A more accurate translation would probably be "the likes of you", but that seemed too old fashioned for this sentence

You can basically think of it as お前に好かれたくない with a なんか/なんて added in.

Now I'm not sure who the subject of that sentence is supposed to be. Maybe if we had more context....

This seemingly asinine thread has turned out to be good practice for us all. If only we had just got to translating and compared notes right off instead of trying to make the OP learn something
